How to remove these ugly urls – Bb_filter = & bb_orderby = & bb_category =?

Hi @thelovebridges
You can try following codes to change CPT slug.

add_filter( 'register_post_type_args', 'bbwp_register_post_type_args', 10, 2 );
function bbwp_register_post_type_args( $args, $post_type ) {

    if ( 'bb_project' === $post_type ) {
        $args['rewrite']['slug'] = 'project';
    }

    return $args;
}

For category and filter, it will need to edit the plugin files, you can search and replace with your desired one.
